1. Agholor is ready to go: USC has been fortunate to have a pair of dynamic receivers recently in Woods and Lee. With Woods taking his talents to Buffalo, the question of who will fill that second receiver spot was answered resoundingly in the spring with a terrific performance by Agholor. It’s not a complete surprise to see this happen, as Agholor had shown flashes as a true freshman, but it was a bit of a shock to see him at such a high level. With Lee sidelined for much of spring with a minor knee injury, Agholor stepped up and was the most consistent offensive performer of spring.

2. New defense gets positive reviews: The offseason arrival of defensive coordinator Clancy Pendergast also brought a new 5-2 scheme for the Trojans, and there was a lot of anticipation to see how things would fit. After 15 practices, the results were fairly solid, especially in the front seven. The defensive line looks strong in the middle -- led by Williams and George Uko -- while Breslin picked up where he left off last fall with 3.5 sacks in the spring game. Pullard looks set at one inside linebacker spot with much-improved Lamar Dawson and Anthony Sarao still fighting it out for the other open spot.

3. Early enrollees as good as advertised: The Trojans took advantage of the early enrollee signing period by bringing in seven freshmen to take part in the spring session. It was a star-studded group led by QB Max Browne and S Su'a Cravens. All seven had moments showing why they were so highly touted with the most impressive all-around performance coming from tailback Justin Davis, who had Lane Kiffin saying he could push for the starting job in the fall.

Fall questions

1. Quarterback battle: The most high-profile position battle didn’t get settled in spring, but that’s not necessarily a bad thing. Sometimes when there is no decision, it’s because nobody is playing well -- that’s not the case here. Cody Kessler and Max Wittek have both shown enough to take over the starting spot after being in the program for two full years. Kessler was steady and came away with the unofficial nod as the projected starter from most practice observers. Wittek missed some time with a knee injury but still showcased the strong arm that will keep this battle going into fall camp. Browne will likely redshirt this year behind those two, but his talent is obvious.

2. Filling the cornerback spots: The need to get things settled at cornerback is the biggest concern coming out of spring. There were simply too many big plays from the USC receivers against a defensive scheme that needs the corners to be effective in coverage. It’s such a glaring problem that Kiffin said he will likely move Josh Shaw from safety to corner in the fall. Shaw had played corner last fall, but he moved to safety in the spring and was the best player in the secondary. The good news is that the Trojans should have plenty of bodies at safety to absorb the loss.

3. Impact of injuries and physical practices: There was a lot made of the fact that the Trojans were going to increase hitting in practice as part of the plan to be more physical in 2013. Kiffin had elected not to hit last fall in part to keep the team healthy with reduced roster numbers, but he ultimately decided that tackling in practice was simply too necessary. Then the injuries started to hit and by the time the end of spring rolled around, the Trojans had 20 players on the sidelines with various ailments, and they couldn’t tackle in the spring game. It’s unclear what the practice policy will be in the fall on this important issue.
